DRILL-PRESS.

Specification of Letters Patent.

Patented June 29, 1915.

Application filed April 14, 1914. Serial No. 831,793.

To all whom it may concern Be it known that I, HENRY G. KAISER, a citizen of the United States, residing at Elk Rapids, in the county of Antrirn, State of Michigan, have invented certain new and useful Improvements in Drill-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in drill presses.

The principal object of the invention is to provide a simple and cheap device of this character which can be readily attached to the ordinary work-bench.

Another object is to provide a simple device of this character which is particularly adapted for use in connection with the ordinary drill-bit brace.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawings.

In the drawings: Figure 1 is a side elevation of the device, Fig. 2 is a top plan view, Fig. 8 is a front elevation, Fig. 4: is a vertical section on the line 4-4 of Fig. 3, Fig. 5 is a vertical section on the line 5-5 of Fig. 3, and Fig. 6 is a horizontal section on the line 6-6 of Fig. 1.

Referring now more particularly to the accompanying drawings, 10 represents a vertical standard provided with a plurality of openings 11 through which are passed clamping bolts 12 to adjustably secure the clamp arms 13 and 14:. The former of these arms has a lower serrated face 15, while the latter of the arms carries a pressure screw 16. These arms are adapted to be passed respectively above and below the top of a work-bench, and the screw tightened to firmly hold the upright in position. On the lower end of the upright or standard is an arm 17 which extends from the opposite side of the standard to that from which the arms 13 and 14 extend, and on the outer end of this arm is a bifurcation 18 which supports a base or drill plate 19 pivotally carried by the arm.

On the upper end of the standard, and 6X- tending over the arm 17 is an arm 20, in the outer end of which is carried a feed screw 21. Carried by the lower end of this feed screw are the jaws 22 of a clamp which receives therebetween the rotary head 23 of the brace 24. This brace is of the ordinary construction and has the drill chuck 25 on the other end.

By means of the openings 11, the clamp arms as well as the arms 17 and 20 can be adjusted to various heights on this standard, to suit the desire of the user.

When the parts are properly adjusted, and the material to be drilled is supported on the plate 19, the brace is rotated to drive the bit into the work. As the bit advances into the work, the brace is fed down by the feed screw 21.

From the foregoing it will readily be seen that I have provided a simple and cheap drill press which can be easily attached to or detached from the ordinary work-bench. Furthermore, the device is adjustable to various heights according to the desires of the user and it will be noted that the ordinary bit-brace can be used in connection with the device.

What is claimed is:

In a drill press, a vertical standard, a clamp carried by the standard for securing the same to a support, a work support carried by the standard, an arm carried by the upper end of the standard, a feed screw carried by the arm, a U frame drill brace including a rotary head, and a clamp carried by the screw for gripping engagement with the said head of the brace.

In testimony whereof, I afiix my signature, in the presence of two witnesses.

HENRY G. KAISER.

Witnesses JACOB KAISER, CLAUDE WATSON.
